Php 如何在3个不同的表中使用while循环回显数据库的特定列

我想从3个不同的表中选择不同的列，并在表数据中显示

我有一张名为“房间”的桌子。我有两个外键，分别是Hotel_id和Room_Type_id。room表中的其他列是price、facilities等。我想使用FK hotel_id从hotel表中获取hotel_名称，使用FK room_type_id从room_type表中获取room_名称

我绞尽脑汁，使用连接分别查询酒店名称和房间类型名称。使用以下查询

//Query to find hotel_name

$query = "SELECT hotels.hotel_name FROM hotels INNER JOIN room ON room.Hotel_Id=hotels.hotel_id";
$res = mysqli_query($connection, $query);
while ($data1 = mysqli_fetch_array($res)) {

//Query to find room_type_name:
 $sel_cus = "SELECT room_type.Room_Type_Name FROM room INNER JOIN room_type ON room.room_type=room_type.Room_Type_Id";
$res_cus = mysqli_query($connection, $sel_cus);
while ($data = mysqli_fetch_array($res_cus)) {

//Query to select price,and picture of room:
    $count=1; // counter to print serial numbers in table
$sel_cus = "select * from room Order by room_id ASC";
$res_cus = mysqli_query($connection, $sel_cus);
while ($row = mysqli_fetch_array($res_cus)) {

// here is code to print record in table

    <tbody>
            <tr>
            <td><?php echo $count;  ?></td>

            <td ><?php echo $data1['hotel_name'];?></td> 
                    <td><?php echo $data['Room_Type_Name']; ?></td>
                <td><?php echo $row['price']; ?></td>




  } // End Query to find hotel_name 


                                   } // End Query to find room_type_name:

} // end of Query to select price,and picture of room

请帮助

您只需使用一个查询即可完成以下操作：

SELECT hotels.hotel_name 
    ,  room_type.Room_Type_Name
    , room.price 
    , room.facilities
    , room.picture 
FROM hotels 
INNER JOIN room ON room.Hotel_Id=hotels.hotel_id
INNER JOIN room_type ON room.room_type=room_type.Room_Type_Id
ORDER BY hotels.hotel_name ,  room_type.Room_Type_Name, room.price 

SELECT hotels.hotel_name 
    ,  room_type.Room_Type_Name
    , room.price 
    , room.facilities
    , room.picture 
FROM hotels 
INNER JOIN room ON room.Hotel_Id=hotels.hotel_id
INNER JOIN room_type ON room.room_type=room_type.Room_Type_Id
ORDER BY hotels.hotel_name ,  room_type.Room_Type_Name, room.price
